6 Claims.

This invention relates to improvements in containers which are of thegeneral character of flat bottomed paper drinking cups and may bemanufactured on known paper drinking cup machines, the invention beinghighly desirable for use in connection with the serving or carrying ofhot liquids, or a cold substance such as ice cream or the equivalent, orother substances, and capable of carrying such substances for aconsiderable length of time without any material weakening of thecontainer, although the invention will have other uses and purposes aswill be apparent to one skilled in the art.

This application is a continuation-in-part of my copending applicationentitled Containers and method of making same, filed March 9, 1940,Serial No. 323,055.

More particularly, the invention relates to a container having amulti-thickness wall to strengthen the container so as to enable thecarrying of hot or cold substances for a comparatively long time withoutmaterial weakening of the container and Without objectionable change inthe temperature of the substance carried.

I am aware that in the past many and various types of multi-Walled papercontainers have been provided, some of which were made from a singleblank of suiiicient length to provide several wraps in the finishedcontainer, and others from a plurality of blanks glued or otherwiseadhesively secured together. However, none of these containers of whichI am aware were capable of being manufactured on known machines forforming single-walled flat-bottomed containers of the character of paperdrinking cups having the shape of va truncated cones. A single blank ofsuilcient lengthto be wound twice around in the form of a container bodyresults in too great a wastage of paper stock in the cutting of theblank, and it is too difficult to handle such a blank in cup-formingmachines of the ordinary type, owing to the undue length of the blankand the high degree of accuracy with which it must be fed to the machinein order to provide a cup with the edges of both laps in properregister. Further, in most cases of multi-thickness containers asheretofore known, the resultant container was not of a nicely balancedconstruction, in that a heavy seam ywould be provided in one place onthe container, and nothing opposite that seam in order to providestability and balance throughout the container. Such was especially truein the case where a single long blank was wound twice or more around toform the container body.

With the foregoing in mind, it is an important object of the presentinvention to provide a container in the nature of a truncated conicalpaper drinking cup, having a multi-thickness wall and which may bereadily manufactured upon known automatic cup-forming machines, whichhave been designed either for forming a similarly shaped container withbut a single thickness wall, or which might be produced by such machinesafter a very slight adjustment.

Another object of the invention is the provision of a multi-walledcontainer made from a composite blank consisting of a plurality ofinitially separate blanks, which blanks are secured together in a mannerto be handled as though they were a single blank, in the forming of thecontainer body.

A further object of the invention is the provision of a multi-walledcontainer of the character of a truncated conical paper drinking cup,which is made from a plurality of initially separate body blanks joinedinto a single composite blank, of such shape as to result in aconsiderable saving of material in the cutting of the blanks.

Still a further feature of the invention is the provision of a containerhaving a multi-thickness wall in the body portion thereof, arranged soas to provide seams evenly spaced around the circumference of the wallto give more strength to the container and to provide a better balancingof this strength throughout the container as a whole, to thus provide agreatly improved container.

'I'he invention also contemplates the provision of a multi-thicknesscontainer of the general nature of a truncated conical paper drinkingcup, having a bail associated therewith in such a manner that the bailwill not come in contact with the contents of the container, and thecontainer being so formed as to provide additional wall thicknesses atspaced intervals so that no additional structure need be provided on thecontainer for the accommodation of the bail.

Another feature of the invention is the provision of a paper containerhaving a multi-thickness wall and made from a composite blank ofinitially separate pieces of stock, wherein the several wall thicknessesmay be of different materials, different colors, and certain of whichmay be printed or not, as may be desired, with the composite blank soformed being treated as a single blank in the formation of the containerbody.

It is also a feature of this invention to provide cated conical paperdriking cup from a composite blank made up of as many initially separatepieces as there are thicknesses between seams in the resultant containerwall, each one of such separate pieces being smaller than a single blankfor making a single thickness container body of substantially the samesize, and in many instances certain of the pieces going to make up thecomposite blank being considerably smaller than such individual blanksfor a single thickness container wall.

Still another object of this invention resides in the provision of amulti-thickness container of the character of a paper drinking cup inthe general shape of a truncated cone wherein a portion of the bodyisturned around a ilange on a bottom member, and the construction is soarranged as not only to provide a very marked saving of material in theprovision of the composite blank going to make up the container body,but also to provide a container wherein the weight of a full containerresting upon a surface will not be entirely carried by that portion ofthe body which is turned in around the bottom member; and, if sodesired, the construction may be carried out so that the weight of thefull container is carried by means entirely to one side of the bottomfold-over portion.

As shown on the drawings:

With reference to Figures l to 6, inclusive,

it will be seen` that the rst form of body blank and container made inaccordance with this invention includes a body blank seen more clearlyin Figure 1, which is made is made up of a pair of initially separatepieces I and 2 secured together in the overlapping portions thereof byadhesive 3 or equivalent means which substantially covers the entireinside face of the piece I. In this instance, the two blanks areoverlapped for substantially half the length of each blank, so that theresultant composite blank is approximately 11/2 times as long as eitherof the pieces i and 2. In the resultant container body, the stock pieceI will be disposed on the outside, and the stock pieceA 2 on the inside.

The initial pieces I and 2 are of substantially similar shape and eachcomprises an arcuate piece having a curved edge at one end to form aportion of the mouth of the nished receptacle, a curved edge at theother end for association with the bottom member to be later described,and a pair of converging straight side edges. 'I'he blanks I and 2 arearranged so that the curved mouth-dening edges coincide in theoverlapped'regions to provide a complete edge 4 which extends twicearound the mouth edge of the resultant container. The outer blank pieceI is Wider than the inner piece 2 and elxtends below the inner blank, asindicated at 5, to provide a margin for association with the bottommember of the nished container. The inner piece 2 is also provided witha stripe of adhesive 6 at its inner lower margin for association withthe outer side of the ange on the bottom member, and also'with anadhesive stripe 'I adjacent its inner end margin to provide a side seamwith the outer end margin. The outer end margin of the inner piece 2preferably has an outstanding central portion 8 deined by oblique endcuts S11-8a, leaving the portion 8 free and devoid of adhesive 6, to begripped by forming means.

4It will be seen that with the blanks overlapped to substantially halfthe length of each blank. the composite blank will form a double-walledcontainer when wound one and one-half times around, and thus provide atriple ply seam at two opposite points in the container body.

It will be appreciated, of course, that a considerable saving inmaterial results in the cutting of the two initially separ .ite blankpieces I and 2 from a sheet or ribbon of stock, over the cutting of asingle long blank which is wound twice around to provide a doublethickness container body. In cutting a blank suiciently long to be woundtwice around, there is considerable wastage between the adjacent arcuateedges of successive blanks, and the triangular waste portions resultingfrom the cutting of the converging side edges are rather considerable insize. In cutting the pieces I and 2 for the composite blank, the wastespace between adjacent arcuate edges of adjacent blanks is relativelysmall, and the triangular shaped waste piece resulting from the cuttingof a converging edge is frequently less than half the correspondingtriangular waste piece resulting from the cutting of a blanksufliciently long to be wound twice around. It will be noted that theresultant saving of material varies to some extent, depending upon thesize and shape of the resultant container. For instance, the savingresulting from a comparatively high and slender container will bedifferent from the saving resulting from a squat container.

although in any instance the saving should not be less than 10 percent,and frequently exceeds 20 percent, so that on the average it mightfairly be said that a 15 per cent having results from the practice ofthe principles of the present invention in the manufacture of the blanksand cups embodied herein. This represents a very substantial andconsiderable saving in this type of manufactured product.

The container of which the body portion may be made from the blank seenin Figure 1 is illustrated in Figures 2 to 6 inclusive. The containerincludes a. bottom member 9 having a depending annular dangle I0. Theprojecting marginal portion 5 of the blank piece I is turned inwardlyand upwardly around the flange I0, as seen clearly in Figure 4, to unitethe bottom member 9 to the body portion of the container made up fromthe composite blank. When the composite body blank is wound intocontainer shape, a pair of triple ply seams I I and I2 are provided onopposite sides of the container. In other words, these seams are spacedequidstantly around the circumference of the container so as to providegreater strength and better balance and stability to the container as awhole. When the body portion is wound about the bottom member, theadhesive stripe Ii unites with the flange I0 on the bottom member, andthe adhesive stripes l and 8 establish seams II and l2.. At the mouthend, the container is preferably provided with a downwardly turned orrolled rim bead I3, which not only provides a smooth drinking or pouringrim but adds to the general strength and stability of the container. Asuitable distance below the rim bead I3, the container is internallygrooved to provide an outwardly extending hollow bead I4, and the groovethus formed in the provision of this bead functions as a seat for asuitable disk cap or closure I5 (Figure 6) which may be used, ifdesired, to protect the contents of the container.

Preferably between the annular bead Il and the rim bead I3, thecontainer wall may be provided with a pair of apertures to accommodatethe ends I6 and I1 of a bail I8, these apertures preferably beinglocated in the triple-ply side seams II and I2 so as to provide areinforced anchorage for the bail. In applying the bail to thecontainer, which may be done after the container has been filled, it isonly necessary to spring the ends I6 and I1 into position, where theywill remain, due to the inherent tendency of the bail to contract. Itwill be noted that still further support for the bail is given by therolled rim bead I3, and it should also be noted that the inner ends I6and I1 of the bail extend inwardly in position'over the cap I5, so as toprevent accidental dislodgement of the cap. When it is desired to removethe contents of thc container, it is a simple expedient to remove thebail wire by withdrawing the ends I6 and Il thereof from the containerbody, whereupon thc cap may be readily removed.

With this arrangement it will be appreciated that the cups or containersmay be made and assembled in stacked relationship, and so delivered tothe retail dealer or user. The bails may be provided in a separatepackage. Thus, much less space is occupied than would be the case if thecups were delivered to the user with the bails already attached.Consequently, it is a simple procedure for the user to remove a cup orcontainer from a handy dispenser, ll the container with the desiredcontent, insert the cap I5 and, if a bail is desired, attach it to thecontainer. If no bail is desired, then no bail is wasted.

A novel method for making the blank seen in Figure 1 and the containerabove described, as well as the other blanks and containers to be laterdescribed herein, is more fully set forth and claimed in my aforesaidcopending application.

In Figure 'l I have illustrated another form of composite. blank, whichresults in a still greater saving of material over the composite bodyblank seen in Figure 1. In this instance the composite blank is made upof two initially separate pieces I9 and 2li secured together in echelonarrangement by the adhesive 2| or the equivalent, which preferablycovers the entire inner face of the piece I9. The added saving inmaterial results fromthe fact that the pieces I9 and 20 are ofsubstantially the same size. whereas, in the blank seen in Figure l, theouter piece 1 was of greater width than the inner piece 2.

The echelon arrangement of the initially separate pieces I 9 and 20 ofthe blank of Figure 'l leaves a margin 22 of the outer blank I9projecting beyond the inner blank at one side edge, and a margin 23 ofthe inner blank projecting beyond the outer blank at the opposite sideedge of the composite structure. Likewise, a margin 24 of the innerblank projects above the outer blank. and a margin 25 of the outer blankprojects helow the inner blank. A suitable stripe of adhesive 26 may beprovided on the inner blank adjacentthe lower edge thereof forengagement with a bottom member, and a stripe of adhesive 21 may beprovided on the inner end margin for establishing a side seam connectionwith the margin 23 which, in the main, is free and devoid of adhesive sothat it may be gripped by forming means.

In forming the composite blank of Figure 7 into the body portion of acup or container, only one revolution of the composite blank isnecessary. The body blank is wound around a bottom member 28 having anannular dependingilange 29 which, in the resultant cup as seen in Figure8, is engaged by the protruding margin 25 of the outer blank piece.After the winding of the composite blank, the protruding margin24 of theinner blank piece is turned outwardly and downwardly over the upper edgeof the outer blank piece, to provide a curled rim bead 30, and spacedinwardly from this rim bead an outwardly 'projecting hollow bead 3| maybe provided to establish an internal cover-receiving groove.

In Figure 10 I have shown a sectional view of a container which may bemade from the composite blank of Figure 7. It will be noted that inwinding the composite blank, the two side edges of each blank piece maybe brought into abutment so as to provide a smooth ush butt-seam 32,whereby no portion of the body part of the container is thicker than anyother portion. Thus, a balanced construction is provided, and with thisconstruction a. bail may be used in the manner above described, althoughthe bail will not have as many thicknesses of stock for its anchorage asis the case in the structure shown in Figure 6.

It will be further noted that iny reference to Figure 8 I have shown theblank piec l5 and 20 as of different thicknesses, to indicate not onlythat they may be of different thickness, but of a different quality ofstock. Obviously, either blank may be of a different color than theother, printing may be provided on one of them, and such variations inconstruction as may be desired for a particular usage may thus besupplied. This is, of course, true with any of the composite blanksdiscussed in this Specification.

It might also be desirable to have an outside bottom member matching incolor or other decoration with the outside of the container body, andwith this in mind I have illustrated, in Figure 1l, the use of such asecond bottom member. It will be seen that the bottom member 28 isdisposed in its usual position and the bottom member 33 is nested withinthe bottom member 28. The margin 25 of the outer blank piece is thenengaged around the depending flanges on both bottom members.

v It should also be noted that it is not essential that the compositeblank of Figure 7 be formed into a, butt-seamed container body as seenin Figure 10. If so desired, a lap seam of the character seen in Figuremay be used. In that event, the container will be thicker at the seamthan anywhere else in its body portion.

In Figures 12, 13 and v14, I have illustrated another form of compositeblank and cup or container made therefrom. This composite blank isformed so as to provide a double thickness fold-up over the ange of thebottom member in the completed cup. In this instance also, I have shownhow a blank of the general character of the blank of Figure 'l may beused to provide a lap seam in the completed vessel, rather than thebutt-seam previously described. 4 e

In this instance, an outer blank space 34 and an inner blank piece 35are secured together in echelon arrangement by means of adhesive 36 orthe equivalent which substantially covers the en-` tire inner face ofthe piece 34, in a manner to provide a projecting margin 31 of the outerblank on one side, and a projecting margin 38 of the inner blank on theother side, with a projecting margin 39 of the inner blank at the top ofthe composite blank. 'I'he inner blank is somewhat wider than the outerblank, so that at the lower edge of the composite blank the two blankpieces lare coincidental. For a lap joint three stripes of adhesive arepreferably utilized, namely, adhesive 36 on the projecting rmargin 31,stripe 40 on the inner end margin oi piece 35, and a curvate stripe 42on the inner bottom margin of the piece 35 vof sufilcient width forengagement with both sides of a bottom flange member. I'he margin 38 isleft free for gripping by forming mechanism.

When the composite body blank is rolled onceI around a bottom member 43having a depending flange, the lower marginal portion of both blankpieces 34 and 35 are turned around the ange of the bottom member, asindicated at 45 in Fig. 14. If so desired, two bottom members may beused, as shown in Fig. 11. The winding of the composite body blank alsoresults in a quadruple thickness lap seam 46, as seen in Fig. 13, but.as before explained, a butt seam of the character seen in Fig. 10 may beutilized with the yblank of Fig. 12, if so desired. For the samecapacity cup, a butt seam provides an added saving long as is necessaryto provide a lap seam or the character of the seam 46 and still maintainthe saine capacity. The body pieces 34 and 35 may be of differentquality stock, different colors. diierent thicknesses, and one maycontain printing or not, as above described.

In Figures 15 to-19, inclusive, I have illustrated another form of blankand container embodying the principles of this invention, wherein thecontainer body is given still an added thickness of material, resultingin a triple-ply wall with quadruple ply seams, andthe design is such asto transfer some oi' the weight of the filled container away from thebottom fold-up around the ilange of the bottom member or members.

In this instance, a composite blank is made up of three initiallyseparate' pieces 41. 48 and 49. the two outer pieces being overlapped onopposide sides of the center piece 48 and secured thereto by adhesive orthe equivalent. With reference to Figure 16 it will be seen that theinside blank piece 49 is slightly wider than the outside and middlepieces 41 and 48, so as to provide a projecting margin 58 which will beat the lower end of the finished vessel. At the upper side, all of theblank pieces are in alignment so as to provide a relatively continuousmouth defining edge.

In forming a container, the composite blank is rolled around a bottommember or bottom members, two members 5| and 52 in nested relationshipbeing illustrated in Figure 18. The composite blank is rolled with thewider piece 49 on the inside and is turned a fraction of a turn over tworevolutions in order to provide the cup body. Three seams of quadruplethickness, 53, 54 and 55 will thus be provided, spaced equidistantlyaround the circumference of the cup or, in this instance, substantiallyapart, center to center. The triple thickness wall, plus the quadruplethickness seams spaced equidistantly, provides an exceptionally strongand stable cup. As seen in Figure 18, the protruding margin 5I of theinner blank piece 49 is folded over around the depending flanges of thebottom. members 5I and 52 in order to unite the body and bottom of thecup. The other body blank portions 41 and 48 terminate flush with thefold-over of the margin 50 as indicated at 56 in Figure 18, so

that the lower edges of these outer blank pieces rest upon the samesurface with the bend of the would be acting if the body of thecontainer was also only of a single thickness.

The triple thickness cup may also be provided at its mouth and with arolled rim bead 51 and with an outwardly projecting hollow bead 58spaced somewhat inwardly from the rim bead in order to provide aninternal groove for a cover member if the same should be desired. It isclear that a bail might be used with the cup shown in Figures 17 and 18by simply providing a. pair of apertures between the rim bead and thebead 58 to accommodate the bail ends as above described in connectionwith the showing in Figure 6. Obviously, also, the pieces 41, 48 and 49going to make up the entire composite blank may be of dierentthicknesses, different qualities, different colors, and certain of themmay be provided with printing, if desired. only one bottom member isdesired, as shown in Figures 4 and 8, only one, of course, need be used.

In Figures 20 to 22, inclusive, I have shown still another form ofcomposite blank and the cup made therefrom, embodying principles of thisinvention. The composite blank seen in Figure 20 results in a greatersaving of material than any of the other composite blanks discussedhereinabove.

Figure 20 is a plan view of the inner face of a composite blankincluding an outer blank piece 59 and an inner blank piece 60, joinedtogether in overlapping relationship for substantially half their lengthand held by a suitable adhesive 8l or the equivalent. In this instancethe adhesive 6I is carried over substantially the entire inner surfaceof the outer blank piece 80, so that when the composite blank is rolledthe outer piece is cemented to the inner piece all the Way around. Theinner piece 59 is wider than the outer piece 80 so as to leave arelativelywide margin 52 of the inner piece projecting above the outerpiece, and also to leave a margin 63 of the inner piece projecting belowthe outer piece. A stripe of adhesive B4 is preferably provided adjacentthe inner side margin of the inner piece 59 forengagement with theopposite and outer side margin of the same piece to provide a seam.66seen in Fig. 22 when the composite blank is rolled into a cup body.Likewise, a curvate stripe of adhesive 65 is provided for engagementwith a bottom member 61 having a depending ange 88, seen in Fig. 21. Theouter side or end margin of -the inner piece 59 is left free forgripping engagement by forming means.

When the blank is rolled about the bottom member 61 into containershape, the ange p'ortion 63 projecting from the lower portion of theinner blank 59 is folded inwardly about the flange E8 of the bottommember in the manner previously described. However, the outer blank isof suflicient width to extend slightly below the bend of this bottomfold-over seam, as indicated at 59 in Figure 2l. This portion 69 is freefrom the adhesive 6|, as shown in Figure 20, the adhesive 5I coveringthe entire face of the outer blank 80 except for this norrow margin 58.Thus, with reference to Figure 21, it can be seen that the entire weightof the filled vessel will be carried by the outer blank piece 60 alone,the lower edge of which is the only portion of the cup contacting thesurface upon which it may rest.

In the completed vessel, a rolled rim bead 10 may be provided, andspaced therebelow a hollow outwardly `projecting bead 1I may be formedto provide an internal cover groove. Both the bead 10 and the groovebead 1l are formed in only the projecting marginal portion 62 of theinner blank piece 59. Obviously, the container seen in Figures 21 and 22may be made on known cup-forming automatically operating machines,because in the fold-over at the bottom seal of the container themechanisms are only working upon a single thickness of material, and thesame is true with respect to the provision of the groove bead 1| and therim bead 10. In this particular form of the invention there is provideda double walled receptacle highly desirable for use in connection withthe packaging of hot or cold sub- 25 stances, a vessel havingconsiderable strength and stability,` and yet one wherein a great savingof stock is provided in the manufacture of the container, and one inwhich the weight of the vessel is transferred from the bottom fold-upseam, so

as not to place any added strain upon this seam, a feature especiallydesirable upon occasions where the cup is left filled with a hot liquidfor a considerable length of time.

. It is obvious, 0f course, that the container of Figs. 21 and 22 may bemade with either one or two bottom pieces, as desired, and ,the blankpieces 59 and 'E0 may be of different quality, color, thickness, etc.

From the foregoing, it is apparent that I have provided an inventionembodying a novel container having a multiply wall, which is exceedinglysimple in construction, yet entirely rigid,

extremely durable, and perfectly balanced. Moreover, the construction ofthe vessels embodied in this invention is contingent upon a very markedsaving of material. It will also be appreciated that the inventionreadily adapts itself for optional use with a bail, which not only maybe readily attached to the container but, when attached, does not comein contact with the contents of the container, and actually aids inmaintaining the cover in position over the contents. Further, theinvention embodies certain features of construction whereby the weightof' a filled vessel is partially or wholly transferred from thefold-up-seam at the bottom of the vessel.-

It will, of course, lbe understood that various details of constructionmay be varied through a wide range without departing from the principlesof this invention, and it is, therefore, not the purpose to limit thepatent granted hereon otherwise than necessitated by the scope of theappended claims.

I claim as my invention:
